The Difference RFID And NFC - Starting from hearing a conversation to talk about what exactly the difference of RFID and NFC, then I'm interested in googling and looking for information about the differences of both of these technologies.
The first is a blog site that is indeed moving in the RFID business. In a blog written what a difference the RFID and NFC briefly and at length. I will cite differences in brief,
Radio frequency identification (RFID) is a technology that uses communication via electromagnetic waves to change data between terminals with an object such as product goods, animals, or humans for the purpose of identification and Search trail through the use of a device called the RFID tag.
RFID tags can be active or passive. Passive RFID tags do not have their own power supply, so the price is cheaper than active tags. With only armed with electrical induction on the antenna caused by the presence of the incoming radio frequency scanning, is enough to give enough strength for RFID tags to send the response back. In the absence of power supply in the RFID passive tag then it will lead to increasingly small size of RFID tags that may be created, even thinner than a sheet of paper with a different range of distances ranging from 10 mm up to 6 meters. Active RFID tags have their own power supply and have the range even further. His memory is also greater so that it can accommodate a wide range of information in it. RFID tags that many circulating right now is the nature of passive RFID tags.
An RFID system can consist of several components, such as tags, tag reader, the tag programming station, circulation reader, sorting equipment, and stick inventory tags. The usefulness of RFID systems is to transmit data from the tags which are then read by a RFID reader and then processed by computer applications. The data that is transmitted and delivered last may contain a variety of information, such as ID, location information or other information.
From an understanding of both the technology is clearly different, RFID (Radio frequency identification), obviously this is using radio and its scope is wider. While the NFC (Near field communication).
NFC stands for Near Field Communication essentially creates a communication between two devices by means of menyinggungkan or hold the two devices at a distance of up to a few centimetres only. The NFC has a range of narrower or just for data exchange at close range, or normally done peer-to-peer in its implementation.
In its Implementation, RFID is more often used for inventory storage shed on a large scale. The use of RFID will facilitate logging of goods without having to do the scans per unit of goods. Simply pass the radio frequency or a reader, then automatically detects the information goods.
Meanwhile, NFC transactions used in close range, on its implementation is usually used for data exchange, such as exchange rate distance contact between smartphones, electronic money transactions or absences.
That's about The Difference RFID And NFC. Thank you.
